What is your rig?
Tracker/Kick go with a wet kit. I always felt these were safer than a dry kit. Nitrous Express sells an import kit with a single nozzle,made for the import cars,that is a complete kit. It has wiring, arming switch, and a microswitch that comes with the kit.
You can run 35hp setting with no timing or sparkplug changes.
If you need more info or help PM me. Ive ran NOS on cars for years.
Later,
Bill
